in research outputs both quality and quantity are of critical value and evaluation of both aspects is required for best evaluation. several studies have worked on single or two-dimensional methods that provide the assessment of quality, quantity or both simultaneously in different branches of sciences, but none of them have played a role in a particular area of medicine. this study has been con...

Uniformly redundant arrays (URA) have autocorrelation functions with perfectly flat sidelobes. The URA combines the high-transmission characteristics of the random array with the flat sidelobe advantage of the nonredundant pinhole arrays. A general expression for the signal-to-noise ratio (SNR) has been developed for the URA as a function of the type of object being imaged and the design parame...

In this paper we investigate threshold based networks performing 2 1 addition using redundant binary operand representations. In particular we concern with establishing the networks with the smallest network depth assuming small weight and fan-in values. First we propose a depth-4 implementation and we show that the 2 1 addition can be computed by a threshold network with the size in the order ...

Coded aperture imaging uses many pinholes to increase the SNR for intrinsically weak sources when the radiation can be neither reflected nor refracted. Effectively, the signal is multiplexed onto an image and then decoded, often by computer, to form a reconstructed image. We derive the modulation transfer function (MTF) of such a system employing uniformly redundant arrays (URA). We show that t...

objective: several studies have compared ferric sulfate and formocresol pulpotomy in primary molars. the results of these studies, however, could not be compared due to differences in evaluated outcomes (clinical, radiographic, or histologic) and follow up duration. the aim of the present study was a systematic review of similar studies and a metaanalysis of their results to provide the latest ...

to present the basic principles and standards of ethics in medical research and publishing, as well as the need for continuing education in the principles and ethics in science and publication in biomedicine. an analysis of relevant materials and documents, sources from the published literature. investing in education of researches and potential researches, already in the level of medical schoo...

This paper proposes a control theoretic formulation and a controller design method for the feature-based visual servoing with redundant features. The linear time-invariant (LTI) formulation copes with the redundant features and provides a simple framework for controller design. The proposed linear quadratic (LQ) method can deal with the redundant features, which is important because the previou...
